Mechanical properties and corrosion rate of iron and iron alloys (Adapted with permission from Ref. [36]. Copyright @ 2014, Elsevier).
| Fe and Alloys | Yield Strength (MPa) | Tensile Strength (MPa) | Maximum Elongation (%) | Corrosion Rate * (mm/year) |
|---|---|---|---|---|
| Young’s modulus—200 GPa, density—7.8 g/cm3 | ||||
| Pure iron as annealed | 150 | 200 | 40 | 0.1 |
| Fe-21Mn-0.7C as recrystallized | 345 | 980 | 62 | 0.13 |
| Fe-21Mn-0.7C-1Pd as recrystallized | 360 | 970 | 64 | 0.21 |
| Fe-10Mn forged | 650 | 1300 | 14 | 7.17 |
| Fe-10Mn-1Pd forged | 850 | 1450 | 11 | 25.10 |
| 316L SS | 190 | 490 | 40 | - |
* Corrosion rate data were collected from those having the most similar experiments, i.e., in simulated body fluid at 37 °C using polarization test, but they may not be directly comparable due to possible variation in specific testing condition and parameters.
